Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991704, here are decompositions:

11 + 991693 = 991704
41 + 991663 = 991704
53 + 991651 = 991704
61 + 991643 = 991704
71 + 991633 = 991704
83 + 991621 = 991704
97 + 991607 = 991704
101 + 991603 = 991704

Showing the first eight; more decompositions exist.
